Abstract

The invention discloses a warming mask with breathing pipes, relates to the field of designs of masks, and particularly relates to the design of warming masks used in winters. In winters, cold air continuously attacks due to cold weather, people can be infected by rhinitis, throats and eyes of people further can be affected by the rhinitis, and then sleep quality, hearing and learning ability are also affected. A common thin cotton mask cannot keep warm while a common thick cotton mask has an obvious retardation effect to air. In order to overcome the retardant effect of the common mask to the air, a plurality of soft and transparent plastic pipes are inserted into an interlayer of the mask to increase the area of air access channels. The technical scheme includes that the soft, transparent, non-toxic and tasteless plastic pipes are buried in the interlayer of the cotton mask, exhalant air is prevented from being diffused fast, most of exhalant hot air is mixed with cold air in the pipes, so that air entering noses of people can be warm, and irritation to the noses of people is relieved. Heat of the exhalant air is sufficiently used to heat the cold air, the irritation to the noses of people is relieved, and the risk of rhinitis is reduced.

Description

The resisting cold mouth mask of band ventilation shaft

Technical field

The present invention relates to the mouth mask design field, particularly resisting cold in the winter design of mouth mask.

Background technology

Nose is the passage that gas enters human body, and winter, cold air continues invasion and attack can be caused suffering from nasal catarrh owing to cold weather, and rhinitis can produce a large amount of mucus, causes symptoms such as runny nose, nasal obstruction.Rhinitis also can influence near throat and the eyes the nasal cavity, influences people's sleep quality, hearing and learning ability.

Commonly used the cotton mouth mask is too thin can not keep out the cold, and too thick then have tangible retardation to air, makes difficulty of respiratory quotient, might cause the oxygen supply deficiency, influences the metabolism of human body.

Summary of the invention

For overcoming mouth mask commonly used to the retardation of air, the present invention inserts several soft and transparent in the mouth mask interlayer plastic tube increases the aisle spare that gas passes in and out.

The technical scheme that the present invention solves its technical problem employing is: the resisting cold mouth mask of band ventilation shaft, it is characterized in that: the breather line that in cotton mouth mask interlayer, inserts three soft and transparent plastics, every breather line has three openings, three openings are respectively the pipeline tapping in both ends open and centre position, the pipeline tapping in centre position is positioned at naris position, the both ends open of three breather lines lays respectively at the outer left side of mouth mask, right side and bottom, breather line adopts nontoxic clear PE flexible pipe, breather line is crooked near the nostril, cut a pipeline tapping in bent position, breather line internal diameter 4mm, external diameter 5mm, breather line sew on mouth mask; The immobilization material that is arranged in mouth mask adopts two elastic bands; Cotton mouth mask size covers the nasion at two canthus up to the corners of the mouth and the chin of following face, presents triangle, 4-8 layer gauze.

The invention has the beneficial effects as follows: take full advantage of the heat of breath, make inhaled air no longer cold, alleviate the stimulation to nose, reduce the risk of rhinitis.

Description of drawings

Fig. 1 is the resisting cold mouth mask schematic diagram of band ventilation shaft.

Wherein, 1, mouth mask, 2, elastic band, 3, bridge of the nose lid, 4, breather line, 5, pipeline tapping.

The specific embodiment

The present invention is the plastic conduit of arranging several softnesses on the basis of common cotton mouth mask, plastic conduit is as breather line 4, plastic conduit is crooked near the nostril, cut a pipeline tapping 5 at bending position, breather line internal diameter 4mm, external diameter 5mm preferably adopt nontoxic clear PE flexible pipe, and plastic conduit can sew on and (be equivalent to line plastic conduit is bundled on the mouth mask on the mouth mask, make the plastic conduit position more fixing), the immobilization material that is arranged in mouth mask adopts two elastic bands 2.

Mouth mask 1 is common cotton mouth mask, and size covers the nasion at two canthus up to the corners of the mouth and the chin of following face, presents triangle, 4-8 layer gauze.Elastic band 2 can be around behind brain mouth mask being worn on nose and the mouth, elastic band 2 is divided into two, article one, be positioned on the nose, article one, be positioned on the chin, regulate a pleasant length after putting on mouth mask, in back side of head position each elastic band 2 is made a call to a slip-knot, just can no longer change its length if not feeling very uncomfortable later on, utilize the retractility of elastic, make and wear and to get mouth mask convenient.

The shape of mouth mask guarantees that the bridge of the nose covers the through nasion position, upper end of 3 parts.

Because the gas that most of nose is breathed out mixes in breather line 4 with the gas that enters nose, the gas heating that colder air is breathed out by nose guarantees that the gas that nose sucks can be too not cold, and reducing cold air stimulates schneiderian membrane to cause the risk of rhinitis.

Claims

1. be with the resisting cold mouth mask of ventilation shaft, it is characterized in that: the breather line that in cotton mouth mask interlayer, inserts three soft and transparent plastics, every breather line has three openings, three openings are respectively the pipeline tapping in both ends open and centre position, the pipeline tapping in centre position is positioned at naris position, the both ends open of three breather lines lays respectively at the outer left side of mouth mask, right side and bottom, breather line adopts nontoxic clear PE flexible pipe, breather line is crooked near the nostril, cut a pipeline tapping in bent position, breather line internal diameter 4mm, external diameter 5mm, breather line sew on mouth mask; The immobilization material that is arranged in mouth mask adopts two elastic bands; Cotton mouth mask size covers the nasion at two canthus up to the corners of the mouth and the chin of following face, presents triangle, 4-8 layer gauze.
